My scooter will never be where I need it. The bird (or lime or Voi or...) can be picked up where I need it, and left where I don’t.
And just like car rentals for regular users ownership is much cheaper. Tourism or some other niche maker surely exists, but the overhead assuming they need to break even is huge.
(I’m not saying it’s for all, but for me, the shared scooter could not be replaced by having my own, which is the argument that kicked of this subthread)
Bike shares have comparable utility with vastly lower costs, and often can’t break even.
It sounds like the problem is that it's never where you need it. Unless you had 10x as many scooters as people and they were littered literally everywhere.
